[Message part 3 (text/plain, inline)]

It would be nice if Emacs had a command to remove matching pairs of
things so that (with | representing point):

(|let (message "%s" "foobar"))

I could delete the parens around the let function. This should work for
other pairs too:

(let ((foobar "foobar")) (message "%s" "|foobar"))

to delete the quotes around the second "foobar"

I know there are 3rd-party packages that implement this but it seems
like this should be included with Emacs since it's such a great tool for
editing.

Fortunately, Emacs already has such a command named ‘delete-pair’:
it deletes the parens around the let function as in your first
example as well as the quotes in your second example.  It makes
sense to bind this command to e.g. ‘C-x M-(’ to be the inverse of
‘M-(’ (insert-pair)
